FUEL-SUPPLY MEANS FOR INTERNAL-COMBUSTION ENGINES.

Application filed April 23, 1926. Serial No. 104,082.

My present invention has to do with the fuel supply of internalcombustion engines; and it contemplates the provision of means adaptedto enable an internal combustion engine to develop considerable powerand speed with small consumption of gasoline, and this in such mannerthat but little carbon will be present in the engine.

Other objects and practical advantages of the invention will be fullyunderstood from the following description and claims when the same areread in connection with the drawings, accompanying and forming part ofthis specification, in which:

Figure 1 is a side elevation showing my improvement properly arrangedrelative to an internal combustion engine.

Figure 2 is an enlarged vertical section of the liquid container of myimprovement.

Figure 3 is an enlarged View taken at right angles to Figure 1, andshowing the forward screens of my improvement.

Figure 4 is a detail enlarged longitudinal section showing one of thenonireturn valves in the conduits intermediate of the liquid containerand the mounting in which said forward screens are arranged.

Similar numerals of reference designate corresponding parts in all theviews of the drawings.

In Figure 1 I show a conventional internal combustion engine 1 having anexhaust conduit 2, and in close proximity to the ex-' haust conduit 2and in close proximity to the said exhaust conduit 2 I show a hot plate3 of conventional or any other appropriate construction designed toreceive atmospheric air so that such air will be heated by the heatgiven olt' by the said exhaust conduit 2.

I also show in Figures 1 and 2 the liquid container 4 of my improvement,the said container-4 being provided with a pendent normally closed drain5 and having in its interior a baffle plate 6 and a screen 7, the latterbeing preferably of basket form and being fabricated by preference, ofappropriate reticulated material. Leading from the hot plate oranalogous device 3 to the,

container 4 is a conduit 8, the eduction'orifice of the conduit 8 beingdisposed below the said bafile plate 6 as shown in Figure 2. Thecontainer 4 is adapted'to hold in its lower portion a body of water orother appropriate liquid, water being preferably employed except inextremely cold weather,

atwhich time an appropriate oil may be wed in the container 4 in lieu ofwater. 9 the container 4 is provided with a normally closed fillingconduit, Figure 1.

The scheme of my invention contemplates the carrying of heatedatmospheric air lated material, the said screen 11 being preferably ofgeneral cone shape and being disposed in th comparatively large-screen7. From this it follows that en route between the interior of thecontainer 4 and the conduit 10, the saturated air must of necessity passfirst through the screen 7 and then through the auxiliary screen 11, itbeing noted in this connection that the interstices of the screen 11 aresmaller than those of the screen 7 in about the proportions shown inFigure 2, so as to lessen the liability of any impurities reaching theconduit 10 and being carried thereby to the carburetor 12 which ispreferably of conventional type, or ofany other construction compatiblewith the purpose of my invention.

At the opposite end of the carburetor 12, with reference to the conduit10; is a manifold 13 designed to conduct hydro-carbon fuel to theengine, and interposed between the manifold 13 and the adjacent end-ofthe carburetor 12 is a mounting 14, appropriately connected and equippedwith two screens 15 in spaced relation, the said screens 15 beingpreferably of reticulated material as appears in Figure 3.

Connected at their rear ends with the interior of the container 4 and attheir forward endswith the interior of the mounting 14 at points betweenthescreen 15 are conduits 16, said conduits 16 heingpreferably arrangedat opposite sides of the basket screen 7 in the container 4,:1nd beingvided at intermediate points in tlieir lengths with casing enlargements17, Figures land 4, the said enlargement'17 serving to containnon-return valves 18 and-the springs 19 and abutments 20 complementarythereto; and in this connectionitwillbe noted that pro- Q the non-returnvalves 18 are arranged to seat toward the rear so as to, ermit thepassage of saturated air forward y through the conduit 16 whileprecluding the passage of anything rearwardly through the said conduit16.

At 19 in Figure 1 I show the internal combustion engine as equipped witha breather device having a foraminous cap 20, and intermediate of thesaid-breather device 19, and the conduit 8 I interpose a conduit 21, thefunction of which is to conduct heated air from the crank case of theengine to the conduit 8 at a point adjacent to the mentioned hot plate3.

In the practical use of my improvement, heated air will be suppliedthrough the conduit 8 to the interior of the container 4 and in passingthrough said container 4, the said air Will be saturated with moistureand will be cleared of impurities and supplied through the conduit 10 ina clear state to the carburetor 12, and after being commingled withgasoline in the carburetor 12, such air forming with the gasoline a richfuel mixture, will pass through the screen 15 and the manifold 13 to theengine, and as the engine increases in speed, the suction created willbe suflicient to overcome the action of the springs 19 and unseat thevalves 18 so that an auxiliar supply of heated and perforated air Wlllbe commingled with the fuel mixture at a point intermediate of thecarburetor 12 and the engine, with the result that the engine will beenabled to develop greater power, and at the same time the liklihood ofcarbon gathering in the engine will be reduced to a minimum.

Manifestly inasmuch as my improvement assures the supply of heated andmoistened air to the engine together with the fuel, less fuel willibenecessary for the adequate operation of the engine, so that when myimprovements are incorporated in an automobile, the automobile may bedriven for a,

considerable distance with the consumption of a small portion ofgasoline.

It willbeapparent from the foregoing, not'withstandin the capacity offunction ascribed to my improvement, the improvement is sim 1e andinexpensive in construction, is relia le in operation, is well adaptedto withstand the usage to which automobile appurtenances are ordinarilysubjected, and is susceptible-for ready installation in automobiles suchas at present in use.

' I have specifically described the construction and relativearrangement of parts embraced in the resent embodiment of my-inventionin or er to impart "a full, clear, and

' exact understanding of the said embodiment.

I do not desire however to be understood as limiting myself to theconstruction and arrangement illustrated'and described, my inventionbeing defined by my present claims within the scope of whichmodifications may be made without departure from my invention. V

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is 1.
